Product Features
1. Complete Electrical Testing Solution – Two Tools in One Kit
This combo package gives you everything you need for professional electrical troubleshooting. The NCV Series clamp meter handles all your measurement needs – AC/DC voltage, AC current, resistance, diode testing, and continuity checks – while the T02A non-contact voltage tester provides quick, safe voltage detection without touching bare wires. Whether you are an electrician, HVAC technician, or DIY enthusiast, this kit covers every scenario from detailed circuit diagnosis to rapid live wire identification.
2. True RMS Measurement for Accurate Readings on Non-Sinusoidal Waveforms
Both 3266TA and 3266TD feature True RMS (Root Mean Square) measurement with a frequency response range up to 2KHz. This ensures accurate readings even on noisy, distorted, or non-sinusoidal waveforms commonly found in modern electrical environments with variable frequency drives, switching power supplies, and electronic ballasts. Get reliable measurements every time, regardless of waveform distortion.
3. Non-Contact Voltage (NCV) Detection on Both Devices – Double Safety
Both the clamp meter and the T02A tester feature built-in NCV detection, allowing you to check for live voltage without making physical contact with conductors. The clamp meter’s NCV function uses an inductive sensor in the jaws – simply bring it near a wire and the red LED flashes and buzzer sounds when voltage is detected. The T02A takes this further with dual sensitivity modes (High: 12-1000V / Low: 48-1000V) and color-coded indicators – yellow for neutral/weak signal, red for live/strong signal. This dual-layer safety approach protects you from electric shock while testing.
4. Comprehensive Measurement Capabilities – Choose Your Model
3266TA (Essential Model):
AC Current: 2A/20A/200A/600A with 1mA resolution
AC/DC Voltage up to 600V
Resistance up to 20MΩ
Diode test and continuity buzzer (<50Ω)
1999-count LCD display
MAX value hold function
3266TD (Advanced Model – Recommended):
All features of 3266TA PLUS:
3999-count LCD display for higher resolution
Capacitance measurement: 4nF to 4mF
Frequency measurement: 4Hz to 10MHz
Temperature measurement: -20°C to +1000°C (with K-type probe included)
REL (relative value) measurement function
5. T02A – Smart Non-Contact Voltage Tester with Premium Features
The included T02A is not just a basic voltage tester – it is a smart diagnostic tool:
Dual Sensitivity Modes: Switch between High (12-1000V) for tracing hidden cables and Low (48-1000V) to reduce false alarms in normal testing.
Live/Neutral Wire Identification: Instantly distinguish between live and neutral wires – red light means live, yellow means neutral.
Breakpoint Finder: Locate wire breaks along energized AC lines (50/60Hz, 12-1000V) by sensing where the AC signal drops off.
Built-in LED Flashlight: Push-button controlled for working in dark panels and tight spaces.
Laser Pointer: Long-press to activate – perfect for pointing out specific wires or terminals during presentations or team work.
6. Smart Power Management – Never Get Caught with Dead Batteries
Both devices feature auto power-off to conserve battery life – the clamp meter shuts off after 15 minutes of inactivity, while the T02A powers down after 5 minutes. The T02A also includes a low-voltage warning system: when battery drops below 2.4V, it beeps three times and flashes red three times before automatically shutting down. No more guessing when to replace batteries.
7. Large Clear LCD Display with Overload Indication
The clamp meter features a large LCD screen for easy reading even in dimly lit environments. When measurements exceed the range, "OL" is clearly displayed. Low battery indicator shows when it is time to replace batteries – no unexpected shutdowns during critical measurements.
8. Auto Ranging – Hassle-Free Operation
No need to manually select ranges – both clamp meters feature automatic ranging that selects the appropriate range for your measurement. Simply clamp, read, and go. This makes the tool incredibly user-friendly for both professionals and beginners.
9. Versatile Applications
This combo kit is perfect for:
Residential electrical inspection and maintenance
HVAC system diagnostics (especially 3266TD with temperature and capacitance)
Appliance repair
Automotive AC system diagnosis
Live wire identification and breakpoint location











please be noted that only hold the power button for 10 seconds till you hear beep sound the voltage tester pen is turned on, a quick press power button can not power on.
